Where can I get detailed description for fixed bugs in new product updates?

is it somehow possible to get further information about fixed bugs in product updates? There is a bug-number displayed after a bugfix-short description but I would like to get more detailed information if this fix maybe also solves my problem...

I'm sorry but for me this page isn't detailed enough. I'd like to get a more detailed description to each point from the release-note list.

Like what exactly was the misbehaviour in the fix for "Corrected the State Machine dialog initial state drop down(18825)"? Or in "Corrected an issue with editing rich text within the Flexi-task action(15575)", what has been the issue? For e.g. was there a workflow-publishing problem if the rich text field contains more than twenty underlined words (really stupid example)?
